We analyze the collective surface diffusion coefficient, $D_c$, near
first-order phase transitions at which two low temperature phases coexist,
using a lattice-gas model on a triangular lattice. Assuming the local
equilibrium approximation, we obtain, both numerically and analytically, the
dependence of $D_c$ on the coverage and system size near such transitions. Four
specific examples of transitions are considered for illustration. It is pointed
out that the derived results are in fact rather general and not restricted only
to the studied model.
